Total Preload Torque
WARNING: This page is about a different car, the 2008 Infiniti EX35. However, it is still accessible from the selected car via links, so may be relevant.
- Before inspection and adjustment, drain gear oil.
- Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
- Rotate drive pinion at least 20 times to check for smooth operation of the bearing.
- Measure total preload with preload gauge (A) [SST: ST3127S000 (J-25765-A)].
Standard
Total preload torque: Refer to PRELOAD TORQUE .
NOTE: Total preload torque = Pinion bearing preload torque + Side bearing preload torque- If measured value is out of the specification, disassemble it to check and adjust each part. Adjust the pinion bearing preload and side bearing preload.
Adjust the pinion bearing preload first, then adjust the side bearing preload.
When the preload torque is large
On pinion bearings: Decrease the drive pinion bearing adjusting washer and drive pinion adjusting washer thickness.
On side bearings: Increase the side bearing adjusting shim thickness. For select parts, refer to parts information.
When the preload torque is small
On pinion bearings: Increase the drive pinion bearing adjusting washer and drive pinion adjusting washer thickness.
On side bearings: Decrease the side bearing adjusting shim thickness. For select parts, refer to parts information.
- If measured value is out of the specification, disassemble it to check and adjust each part. Adjust the pinion bearing preload and side bearing preload.
